I need a button or bookmarklet to delete the cookies from the current context. Clearing the cache would be another option.

Specifically, I am logged into too many Google sites and have multiple accounts active. If I log out, it logs everything out.

I want to delete the cookies for a given context (eg. on music.google.com, delete cookies for music.google.com but leave cookies for ever other site like accouts.google.com, thus refreshing the page prompts me for which account I'd like to use.

Depending on how Google account logins work, that might not even be possible at all.

Yeah, I'm not fond of web development but I created wrote a bit of JavaScript to do it, but it didn't delete the header only cookies. I thought maybe extensions might have more control

This is a fantastic tool as it also has other information about the domain and you can change the security from here. I'm glad Google has added something official for managing your data on a specific site.
